Did you mention this thread? You'd think this 110 page monster on their own forums would be hard to ignore.

Oh it's actually veeery easy for them buddy. Remember Note 7 ? Burning down houses and Samsung didn't even PAID people's hotels. Anyway I live in Brasil and we can't return products bought in-store for no reason like in the US and most advanced countries so I'm stuck with this phone.

In the service center that I used to work before we had problems with some Samsung and Apple smartphones that had battery drain problem. We tried hard reset, formatting, flashing, even multiple battery replacement and none of that worked. On the end It turns out that these Samsung phones had problem with motherboards. They had some sort of short inside it and that drain the battery all the time, similar like resistor. It's simple bad quality control in the factory that's all. All people that had these kind of issue should return their phones to the stores where they got them and demand to get new replacement phones! It's not normal that you need to use all kind's of battery saving features and tips just to survive a day with the brand new phone!

The problem is is that many of us ordered directly from Samsung, or pre-ordered. We have to go to some shop or something somewhere and give our phone to the repair people so they can act like they did something to it and hand it back to us. How can we ensure to actually get a new phone from them and not just some reset?
